Error: The terraform-provider-digitalocean_v2.31.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Hi @gimeroni-lms,

We recently merged a pull request that should prevent this panic. It will be part of our next release.

#1064

The bug on the Terraform provider side fixed by that PR is that we are not properly handling the error response from the API. Without debug logs, it is hard to determine exactly what API error you are encountering. One possibility is that you are receiving a 403 response due to using a read-only API token. Recently the DOKS API made a change to require a read-write token when accessing the /v2/kubernetes/clusters/<cluster-id>/credentials endpoint:

https://docs.digitalocean.com/release-notes/kubernetes/#2023-10-17

So replacing the read-only token with a read-write token may resolve this problem for you.

[gimeroni-lms]

Solved. Thank you very much for the response!

Could you tell me how did you solved that issue
